Description

Technical Field

[0001] The utility model relates to the technical field of leather weakening, in particular to a leather-covered weakening device for a safety airbag area. Background Art

[0002] The airbag of a car can pop out to protect the people in the car when the car collides. It is an extremely important protection system in the car. The airbag is installed in different positions in the car. For some mid-to-high-end models, the car interior is mostly made of leather. That is to say, after the airbag is installed in the car, leather needs to be installed on the outside of the airbag. When the airbag pops out, the leather needs to be broken to pop out normally. Under normal circumstances, the airbag cannot break the leather, so before installing the leather, the leather needs to be weakened. The so-called weakening treatment, in short, is to cut and leave scratches on the leather, and the scratches are generally I-shaped. However, the cutting depth of leather has high requirements. If the depth is too shallow, the airbag still cannot break the leather. If the depth is too deep, it is easy to cause the leather to be directly damaged and affect the appearance. At present, the cutting method of leather scratches is generally that the CNC cutting machine marks the scratches on the leather, and then the workers use a knife to cut it, but the cutting depth of the workers is uncontrollable, which easily leads to the scratch depth being too deep or too shallow, which does not meet the cutting requirements of the leather. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a leather-covered weakening device for the airbag area to solve the technical problem in the prior art that the depth of leather cutting by workers is uncontrollable.

[0004] In order to solve the above technical problems, the utility model provides a leather covering weakening device for an airbag area, comprising a measuring base, a dial indicator, a weakened base, a connecting block, a height slide and a tool, the dial indicator is connected to the measuring base and the probe of the dial indicator is set upward, the connecting block is slidably connected to the weakened base in a horizontal direction, the height slide is connected to the connecting block, the tool is connected to the height slide and the height of the tool is adjusted by the height slide, the blade of the tool is set downward and the projection of the blade of the tool in the vertical direction falls outside the weakened base, and when the weakened base is placed on the measuring base, the blade of the tool can be offset against the probe of the dial indicator.

[0005] After adopting the above structure, the utility model has the following advantages for a leather-covered weakening device for the airbag area: when the leather is weakened, the weakening base is pressed on the leather, so the lower end surface of the weakening base is equivalent to the upper end surface of the leather, and when the weakening base is placed on the measuring base, the lower end surface of the weakening base and the upper end surface of the measuring base are against each other, that is, they are at the same height, and the dial indicator is reset to zero with the upper end surface of the measuring base as a reference, and then the weakening base is placed on the measuring base, and the blade of the tool is against the probe of the dial indicator, and the height slide is used. Adjust the height of the tool so that the blade of the tool is lower than the lower end surface of the weakened base. The height difference between the blade of the tool and the lower end surface of the weakened base is the depth of the tool when cutting the leather, and the specific value of the depth can be directly read from the dial indicator, so as to adjust the depth of the tool cutting the leather to an ideal value. When cutting the leather, place the weakened base on the upper end surface of the leather, align the blade of the tool with the scratch mark on the leather made in advance by the CNC cutting bed, and move the connecting block to cut the leather. The cutting depth is constant and meets the requirements, preventing the leather from being cut too deep or too shallow.

[0006] As an improvement, a guide rail arranged in the horizontal direction is connected to the measuring base, and the connecting block is slidably connected to the guide rail through a slider; adopting this structure, the sliding of the connecting block and the cutter is more stable, and the leather is cut more accurately.

[0007] As an improvement, the upper surface of the guide rail is provided with a scale set along the length direction of the guide rail, and an indicator block is slidably connected to the guide rail. A locking bolt is threaded on the indicator block, and the locking bolt is made to abut against the guide rail by rotating the locking bolt. With this structure, the position of the indicator block is adjusted according to the required scratch length and fixed with the locking bolt. The distance between the slider and the indicator block corresponds to the length of the scratch. When cutting, the cutting is completed when the slider contacts the indicator block, which is more convenient to use.

[0008] As an improvement, a vertically arranged handle is connected to the connecting block; with this structure, the connecting block can be slid by holding the handle, which is more convenient to use.

[0009] As an improvement, two left and right handles are connected to the top of the weakened base; with this structure, the position of the weakened base needs to be adjusted before adjusting the height of the tool. Since the leather scratch is I-shaped, the position of the weakened base also needs to be adjusted during cutting. The handles are provided to facilitate carrying and moving.

[0010] As an improvement, a plurality of through holes arranged at intervals are provided on the weakened base; with this structure, the weight of the weakened base is reduced by providing the through holes, making it easier to carry and move.

[0011] As an improvement, a groove is provided on the upper end surface of the measuring base, and the probe of the dial indicator is exposed above the groove; with this structure, the blade part of the tool may have been lower than the lower end surface of the weakened base before the tool height is adjusted. The provision of the groove on the upper end surface of the measuring base can prevent the weakened base from being directly placed on the measuring base in the above situation, causing the blade to contact the measuring base and cause wear and blunting of the blade.

[0012] As an improvement, a protrusion is provided on the weakened base and on the side wall close to the tool along the moving direction of the tool, and the protrusion is arranged adjacent to the moving trajectory of the blade of the tool; with this structure, since the height slide and the handle both have a certain width, the blade of the tool will be a certain distance away from the side wall of the weakened base, resulting in the leather at the cutting point of the blade not being pressed by the weakened base, resulting in inaccurate cutting. By providing a protrusion adjacent to the blade trajectory, the protrusion can be used to further press the leather at the cutting point of the blade, making the cutting more accurate.

[0013] As an improvement, the measuring base includes a top plate, a bottom plate and a plurality of columns, the top plate is connected to the top of the bottom plate through the plurality of columns, and the dial indicator is connected to the top plate. BRIEF DESCRIPTION OF THE DRAWINGS
